IMPROVEMENT IN SASH-HOLDERS.

Specification forming part of Letters Patent No. 217,056., dated July 1, 1879; application led March 21, 1879.

To all whom -it may concern:

Be it known that I, ERNST BERNHARDT, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful. Improvement in Window-Sash Locks, of which the following` is a specilication.

This invention is an improved means of locking a window-sash in any desired position. It is especially intended for railroad-car windows.

It consists of the combination of a pivoted cam, a connecting-rod attached with one end to the cam, and a perforated slide, which acts on the other and oblique end of the connecting-rod. These parts are preferably used in duplicate., so thatv the sash may be locked on both sides.

In the accompanying drawings, in which identical parts are indicated by the same letters in the different figures, Figure lis a front elevation of a window frame and sash tted with in y improvements. A portion ot' the frame and sash is broken away to expose the eccentric and connecting` rod. Fig. 2 is a vertical section taken in line :v rr, Fig. 3; and Fig. 3 is a sectional plan taken in the plane of line y y, Fig. 1.

Referring to the parts, A A are cams or eccentrics, journaled upon pins in the vertical rails of the sash, and B B are the actuating or connecting rods. These are bent at a right angle at their outer ends to enter holes in the cams A A. The inner ends of these rods are bent upward at acute angles, and pass through holes in the sliding piece C.

D isV an angle-piece, which is secured upon the lower rail of the sash. The plate by which it is attached to the sash-rail is slotted to form a guide for the slide-piece C, the inwardlyprojecting plate of this piece being perforated to receive the central piece between the slots, and its edges bearing against the outer pieces of plate D, together with flanges on piece C, which turn down over the outer edges of the plate D, and serve to guide the piece C and permit it to slide freely.

E is a spring, secured to the under side ofthe thumb-piece, formed by the angle of piece D. It bears upon the top of piece C, and by pressing it down separates the oblique ends of the wire rods B B, an d forces the edges of the looking-cams A against the window-frames, thus lookin g the sash firmly in any position.

To operate my device to change the sash from one position to another, the pieces C and D are taken between the 'first linger and thumb and pressed together. This, by drawing up the piece C, will draw the inner oblique ends 'of rods B together and release the pressure of the cams A from the frame, when the sash is, by means of the pieces C and D, moved to the desired position. As soon as these pieces are released the spring E will press down piece C, separate the ends of rods BB, and lock the sash by forcing the cams against the frame.

Should it be desirable to lock the sash in the lower position, so that it cannot be opened from the outside, this can be accomplished by notehin g the Window-frame to receive the cams A when the sash is down.

I have shown the edges of the cams A rough cned or notched. This will serve every purpose when hard wood is used in the frame but when soft wood is used a correspondingly roughened or notched plate may be secured on the edge of the frame, to en gage teeth in the cam, or a rubber-edged cani substituted for the one shown.

I claim- The combination, substantially as specified, of the pivoted cam, the connecting-rod havin g an oblique end, the spring, and the perforated slide acting on the oblique end ot' the con* nectiug-rod.

ERNST BERNHARDT.
